FIELD: radio engineering. SUBSTANCE: array has n channel multiresonance (ridge-shaped) opposite-pin converters, m channel strip opposite-pin converters, n+m channel commutators, input and output splitters. Channel and strip opposite-pin converters are disposed onto piezoelectric acoustic line normally in form of columns and lines in common acoustic channel. Inputs and outputs of the converters are connected with input and output splitters through channel commutators. EFFECT: simplification; microminiaturization of the device. 1 dwg
